EUGENE L. MAUPAI, OF NEW YORK, N. Y.

SKEIN-SILK-DYEING APPARATUS.

Specification of Letters Patent.

Patented Jan. 21, 1913.

Application filed April 12, 1912. Serial No. 690,341.

T0 all whom it may concern Be it known that I, EUGENE L. MAUPAI, a.citizen of the United States of America, residing at Bronx borough,city, county, and State of New York, have invented certain new anduseful Improvements in Skein-Silk- Dyeing Apparatus, of which thefollowing is to keep the skeins of silk in motion during the dyeingprocess, the apparatus being or-v ganized to cause the skeins of silk tomove about an axis, the said skeins being vertically disposed relativeto said axis and to cause the said skeins to travel or move in themanner of a belt, while being rotated about the aforementioned axis.

I will now proceed to describe my inven` tion in detail, reference beinghad to the accompanying drawing, forming part hereof, wherein:

Figure 1 is a vertical sectional view, partly in elevation, of myimproved dyeing apparatus; Fig. 2 is a sectional plan view thereof, thesection being taken on a line 22 in Fig. 1; and Fig. 3 is an enlarged,fragmentary, sectional detail view of the rotatable supports for theskeins of silk.

In the drawing which illustrates a preferred embodiment of my invention,the numeral 1 indicates a tank or receptacle designed to retain acoloring or dyeing Huid indicated by 2. In the process of dyeing silk,it is preferable, if not necessary, to keep the coloring fluid at acertain temperature and to maintain the said fluid at the requiredtemperature I provide a coil 3 through which steam or any other heatingclement can flow.

To carry out the object of my invention I provide a rotatable frame orspider 4, the said frame being slidablv mounted upon a rotatable shaft5, which is provided with a feather 6. The feather 6 engages a keyway inthe hub 7 of the frame 4,` by which means the said frame is rotated whenthe shaft 5 is operated. To operate the shaft 5 I provide the same witha gear 8, which meshes with the pinion 9 rotatably mounted in thebracket 10. The gear or pinion 9 is rotated in the form' by means of thepulley 11 and a belt, which is not shown.

To support the skeins of silk in order to cause them to move through thecoloring element, I provide spools 12, preferably made out of porcelain,each of the said spools being fixed to a shaft 13. The shaft 13 alsocarries the gear 14, by which means the said shaft 13 is rotated. Theshaft 13 is rotatably supported in a fork 15, with which each arm 16 ofthe frame 4 is provided. As illustrated in Fig. 2, the frame 4 comprisesa plurality of arms 16, all of which are carried by the hub 7.

To impart to the skeins of silk, which are indicated by 17 in Fig. 1,(two only being shown) a belt-like movement during the rotation of theframe, I provide a rack 18 with which the gears 14 mesh, the said rackbeing, in this instance, formed in the upper end of a circular wall 19in the tank 1, the said circular wall being provided with openings 20for the circulation of the dyeing element. It will be obvious that whenthe frame 4 is rotated, the skeins of silk will be caused to travel in acircular path through the dyeing fluid; at the same time the spools 12will rotate and cause the said skeins to travel in the manner of a belt,or in a vertical plane, around the said spools.

By imparting to the skeins of silk the movements above referred to, allportions of the silk are caused to pass through the d veing or coloringiiuid, and as the said skeins are at no time at rest during the dyeingprocess, no vone partof the skein remains in the dyeing fluid longerthan another part. Therefore the silk is dyed equally throughout.

In order to carry the skeins away from the dyeing` fluid after thedyeing process has been completed, I move the frame 4 upwardly along theshaft 5, by means of a pivotal lever 21, the said lever being providedwith a fork 22, having pins Q3 adapted to take into an annular groove Z4in the frame 4.

To operate the lever 21, I provide the same with a segmental rack 25,having in mesh therewith, a worm 26, the said worm being carried by ashaft 27, provided with a handwheel 28 for turning the same. When theworm 26 is rotated in the proper direction the lever 21 will be thrownupwardly, thereby sliding the frame 4 along the shaft 5 and carrying theskeins of silk 17 out of the dyeing Huid.

To facilitate the removal of the skeins of silk from the spools and alsoto facilitate the placing of skeins upon said spools I movably mount thejaws 15 in the arms 16 of the frame 4, each of said jaws being carriedby a bar 29. Each bar 29 is slidably fitted-in a guideway 30 with whicheach arm 16 is provided, set-screws 31 being provided to secure the bars29 in position in their respective guideways.

Vhen the frame 4 is moved upwardly the jaws 15 and spools carriedthereby may be moved outwardly, when the set-screws 31 are backed off.When the spools have been moved outwardly, as described, they may beeasily gotten at, for the purpose of removing the skeins which have beencolored or for the purpose of placing uncolored skeins thereupon. Afterthe spools have been loaded, the jaws 15 will then be moved inwardly totheir normal position and the setsorews 31 caused to hold them in suchposition. After all the spools have been loaded, the frame 4 is thenlowered until the gears 14 and rack 18 intermesh, at which time theskeins 17 will have entered the coloring iuid. After the frame has beenlowered, the machine or apparatus may be started and operated in themanner described. The tank 1 is provided with an outlet valve 32 throughwhich coloring matter may be drawn off.

Having now' described my invention in detail, what I claim and desire tosecure by Letters Patent is:

1. A dyeing apparatus comprising a tank adapted to retain a coloringelement, a rotatable frame adjacent said tank, radially movable supportscarried by said frame, rotatable spools carried by said radially movablesupports, means for securing said radiallymovable supports, and meansfor rotating said frame and said spools simultaneously.

2. A dyeing apparatus comprising a tank adapted to retain a colorinelement, a rotatable frame adjacent sai tank,j radially movable supportscarried by said frame, a gear carried by each of said radially movablesupports, a rack adapted to mesh with said gears, spools adapted forrotation by said gears, and means for rotating said frame.

3. A dyeing apparatus comprising a tank adapted to retain a coloringelement, a rotatable frame adjacent said tank, said frame comprising aplurality of radiaily disposed arms provided with gui'deways, a barSlidably mounted in each of said guideways, means adapted to secure saidbars iri said guideways, a gear rotatably mounted at the outer end ofeach of said bars, spools adapted for rotation by said gears, arackadapted to mesh with said gears, and means for rotating said frame.

4. A dyeing apparatus comprising a tank adapted to retain a coloringelement, a rotatable frame adjacent said tank, said frame comprising aplurality of radially disposed arms provided with guideways, a barslidably mounted in each of said guideways, 'means adapted to securesaid bars in said guideways, a shaft rotatably supported at the outerend of each of said'bars, a gear carried by said shaft and securedthereto, spools carried by said shaft and adapted to rotate therewith, arack adapted tomesh with said gears, and means for rotating said frame.
